Compact Battery Replacement for Milwaukee 12v: Batteries 4.0 ah Lithium Compatible M12
These batteries are working exactly as expected. These are the compact ones, but they rate them at 4.0 Ah. Overall, they perform well for me. Time will tell how long they last, but so far so good.

A quality alternative to OEM
It fits in my Milwaukee wrenches. It charges in my Milwaukee chargers. It has a comfortable form factor similar to original. It provides a similar if not identical level of power to the tools. Costs less than OEM. Too early to tell about longevity, but thus far this is a winner.

Exactly What I Needed
It was exactly what I needed for my Milwaukee tools. It provides ample power and runtime for most projects without needing frequent recharges. The battery charges relatively quickly and keeps a steady charge even through heavy use. Quite Good.

Batteries don’t latch into tool
I got these to augment some Milwaukee M12 batteries – my tool set came with three tools but only two original batteries. These batteries have a significantly larger capacity for the same size. These are rated at 4.0AH whereas my original ones were only about 1.33AH. I expected great things from these. The red portion fits the original charger well and also fits into the tool handle without binding. However, the black part was either cast too small or shrank after molding. It is visibly smaller than the original when inserted into the tool. Further, the latching prongs do not engage and you can dislodge the battery by shaking vigorously.I would have loved to give this five stars, but the poor fit only deserves three. Not recommended unless you are willing to put up with this.

Good but a little off
Right off the bat the color matches OEM color scheme, so unless you look at the sticker, no one can tell that this is not OEM.I tried to charge it before use , but it was fully charged. It fits the Milwaukee oem charger well. It is detected as a battery.I used it on the drill. The fitment was a little off. I had to force it into a drill. It works just as good as an oem battery.I am unable to test if the MAH capacity is accurate as listed. However it does seem to weight as an OEM battery. The plastics used is of good quality and appear to be durable.I would recommend it as backup batteries!

Nearly Identical…
If it weren’t for the Milwaukee logo on my original batteries, I wouldn’t be able to tell the difference between these. Not just with the physical appearance either, I’ve drained them a few times and so far they perform just as well. They aren’t quite as easy to insert and remove, but it’s barely noticeable and still easy to do. If I hadn’t done it thousands of times I probably wouldn’t notice.

So far so good!
I use my Milwaukee tools quite a bit. I’m always looking for solutions for batteries…especially the 12v ones. These were a good find.They came fully charged, which was a little surprising, but welcomed. I dropped them in my 2569-20- and gave it a spin. Worked like a charm!My only critical observation is that the fit isn’t as precise as the Milwaukee batteries. They still positively connected and worked fine, but they didn’t connect as nicely.Time will tell. I’ve had off brand 18v batteries die after 4-5 charges. But these look great so far!
